George I started with a 997, then got an 1197. I just purchased a 798 for portable use in Canada. I have been very satisfied with HB. I started reading on the BBC when someone posted a link about comparing it to downscan. The results of that test showed a VERY poor result. The individual who did the test has said that downimaging is useless. I mentioned that if it worked so poorly, why were there not complaints being registered in the forums. My intent with this post was to actually see how many were having good or poor results- which I have only seen good so far. The link I posted was a thread not comparing Lowrance with it, but defending the statement that it does indeed scan directly below the boat.
